Normal module mn = 2 mm
Pinion:
- Helix angle B1 = 30 deg., left hand
- Face module ms1 = 2.31mm
- Tooth number Z1 = 15
- Pitch circle dia. D1 = 34.64 mm
Rack:
- Helical teeth, B2 = 13.69 deg.
Angle between pinion axle and rack moving direction is L = B1 + B2 = 43.69 deg.
1 pinion revolution makes rack move Pi.D1.cosB1/cosB2 = 97.00 mm
